Typical Installation Accessories

Install the accessories shown in F
as necessary.
Air Line Accessories
• Bleed-type master air valve (D): required in your
system to relieve air trapped between the pump and
the gun when the valve is closed.
NOTE: Be sure the valve is easily accessible from the
pump and located downstream from the air regulator.
Trapped air can cause the pump to cycle
unexpectedly, which could result in serious injury from
moving parts or splashing fluid.
• Pump air pressure regulator (E): to control pump
speed and fluid outlet pressure. Locate it close to
the pump.
• Air line filter (B): removes harmful dirt and moisture
from compressed air supply. Ensures a dry, clean
air supply.
• Gun air supply hose (H): connects air supply to the
gun. Use a 3/16 in. (5 mm) I.D. or larger air hose to
minimize excessive pressure drop in the hose.
• Gun air pressure regulator (C): controls air pressure
to the gun.
• Air shutoff valve (A): shuts off air to the gun and
pump.

Fluid Line Accessories
• Fluid filter (I): with a 60 or 100 mesh (250 micron)
stainless steel element to filter particles from the
fluid as it leaves the pump. Always use a clean fluid
filter.
• Fluid drain valve (L): relieves fluid pressure in the
hose and gun
• Fluid shutoff valve (not shown): shuts off fluid flow.
Can be installed in the fluid line to the gun.
• Fluid pressure regulator (not shown): for more
precise adjustment of the fluid pressure. Can be
installed in the fluid line to the gun.
NOTE: Systems without a fluid regulator control the
fluid pressure with the pump air regulator, per the
formula:

• Gun fluid supply hose (G): supplies fluid from a
pump to the spray gun.
• Fluid swivel connector (22): for easier gun
movement. Some models include a swivel
connector. See Models, page 3.
